I don't think that Guacamole load balancing does any housekeeping with regard to the status of the systems behind the connections it's balancing across. I think it just keeps track of number of active connections / which users (session affinity) are connected to each connection and then uses that information to choose which one to hand a user to when they connect.
I use haproxy behind Guacamole to balance across RDP servers, with connectivity checks/steering disconnected users back to their correct server, etc. On Fri, Mar 22, 2024 at 11:30 AM Barnhart, Steven <barnhart....@osu.edu> wrote: > Anyone have any info on why this could be happening?
